5 questions from this lesson’s quiz. Start the lesson to answer them and see the right answers.

1. 1. Why must a solid be weighed on the balance BEFORE it is placed in water during a density experiment?

   • A. Electronic balances cannot work in a room with water
   • B. Water clinging to the wet solid adds extra mass to the reading
   • C. The solid loses mass permanently when it is submerged
   • D. The solid will dissolve if it is weighed afterwards

2. 2. A steel bolt has a mass of 156 g. When it is lowered into a measuring cylinder containing 50 cm^3 of water, the water level rises to 70 cm^3. Calculate the density of the bolt in g/cm^3.

   Type your answer (in g/cm^3) in the lesson.

3. 3. A learner measures the volume of a rough stone using a measuring cylinder. Air bubbles stay trapped in the pits of the stone. What effect will this have on the calculated density of the stone?

   • A. The density will be too low, because the measured volume is too large
   • B. The density will be too high, because the measured volume is too large
   • C. The density will be too low, because the measured mass is too large
   • D. The density will not change

4. 4. The water level in a measuring cylinder is 42 cm^3. After an irregular stone is fully submerged, the level rises to 67 cm^3. What is the volume of the stone?

   Type your answer (in cm^3) in the lesson.

5. 5. What name is given to the container with a side spout that is used to measure the volume of large irregular solids by catching the displaced water?

   Type your answer in the lesson.
